possible bug *with versions*

[Mason Mackaman <masondeanm@...>]

sorry, I realized right after I sent the message I forgot to include 
what version I was working with. I've confirmed this happening with 
5.1.4 and 5.2.0.

Hello everyone, I'm pretty new to programming and even newer to Lua, so 
please humor me. I feel I've found a bug but it's most likely just me 
being a noob.


function f(set)
	local newset,cloneset={},set
	for x=1,#cloneset do
		newset[x]=cloneset[#cloneset]
		table.remove(cloneset)
	end
	return newset
end
function

g(set)
	set=f(set)
end
a={1,2,3,4,5,6,7,8,9}
g(a)
print(#a)


This is the simplest form I can put the bug in. I feel like it should 
output 9 but instead it outputs 0. If someone could tell my why this is 
happening I would be much obliged.

info:
- #f(a)=9
- every time table.remove(cloneset) is executed it also executes the 
equivalent of table.remove(a)
